Electrical Galvanized Steel Production Process Introduction

1. Input process: The input point of the electrogalvanizing wire is equipped with a pay-off reel, a shearing machine, a welding machine, a looper, and a tension and straightening machine. Pay-off reels transport stacked or cold-rolled steel to shears, which cut and join them in preparation for welding. Next comes the welding process.

2. Pre-treatment process: Electrolytic cleaning line, consisting of an electrolytic tank, acid bath, and rinsing tank, is used to remove contaminants and oxide films on the surface of steel before electroplating.

3. Electroplating: The CAROSEL method, as well as other electrogalvanizing techniques, involves plating one side at a time using a conductor roller. This process can produce double-sided, single-sided or different-sided electroplated plates. Additionally, the horizontal method allows both sides of the sheet to be plated simultaneously, resulting in a double-sided plated sheet.

4. Phosphate Film Coating: A phosphate film is applied to the surface of the zinc layer through a chemical or electrochemical reaction. The film provides temporary corrosion protection and provides a safe substrate for painting.

5. Anti-fingerprint process: Organic, inorganic or organic-inorganic hybrid films are applied to the surface of steel plates to enhance corrosion resistance and impart desired properties, such as resistance to fingerprint marks and improved processability.

6. Output process: The exit of the production line includes output loopers, tension reels and automatic packaging lines to protect the products after coil winding.
